I went out and had a play with shooting the town in the dark, this is my first time doing this so critique very welcome,
3 shots first is a single shot with only a little bit of raw fettling the second is 3 shots that have been processed through the CS5 HDR function, and then a little messing about just to see what it does, comments and preferences welcome. (Last one is just a crop of the second)
